Fluorescent wheel heat dissipation device

Abstract

Disclosed is a fluorescent wheel heat dissipation device. The fluorescent wheel heat dissipation device comprises a sealed light source channel, a fluorescent wheel arranged in a sealed cavity of thesealed light source channel, a fluorescent wheel radiator arranged on the first side of the sealed light source channel, a light source radiator arranged on the second side of the sealed light sourcechannel and an exhaust fan arranged on one side, far away from the sealed light source channel, of the light source radiator. According to the fluorescent wheel heat dissipation device provided by theinvention, the fluorescent wheel is completely sealed in the sealing cavity of the light source channel, so that the conversion efficiency of the fluorescent wheel cannot be lowered due to ash or dust; the fluorescent wheel and the radiator do not need to be directly connected, so that the structure difficulty and the cost of the system are reduced; due to the coordination of the fluorescent wheel radiator, the light source radiator and the exhaust fan, the temperature of the air in the sealed light source channel can be effectively reduced, so that the fluorescent wheel can meet the workingtemperature conditions under the effects of heat radiation, transmission and air cooling.

Description

technical field [0001] The invention relates to the field of light and laser projection, and more specifically, to a fluorescent wheel cooling device. Background technique [0002] The fluorescent wheel generates a lot of heat in the process of light energy conversion, and it needs to be reliably dissipated to ensure the normal operation of the fluorescent wheel and the motor. The laser fluorescent wheel has limited efficiency in the process of converting a single blue light (or green light, red light) into broad-spectrum light, and part of the light energy generates heat. If it is not cooled in time, the temperature of the fluorescent wheel and the motor will be very high As a result, the fluorescent wheel or motor is burned out, which further leads to the failure of the entire laser optical system. [0003] In the prior art, in order to dissipate heat from the fluorescent wheel, some radiators are directly connected to the fluorescent wheel to dissipate heat, so that the ...

Problems solved by technology

The laser fluorescent wheel has limited efficiency in the process of converting a single blue light (or green light, red light) into broad-spectrum light, and part of the light energy generates heat. If it is not cooled in time, the temperature of the fluorescent wheel and the motor will be very high As a result, the fluorescent wheel or motor is burned out, which further leads to the failure of the entire laser optical system

[0003] In the prior art, in order to dissipate heat from the fluorescent wheel, some radiators are directly connected to the fluorescent wheel to dissipate heat, so that the heat dissipation effect is ideal, but it is difficult to completely seal the light source channel and the cost of the radiator is high; some are equipped with air inlets and outlets Use air cooling to dissipate heat from the fluorescent wheel, which is easy to enter dust and affect the efficiency of the fluorescent wheel. Some aluminum plates that install the fluorescent wheel have a large diameter, which will result in a large light source channel and high cost of the fluorescent wheel.
